Title: Improvements in removing scale from metal surfaces electrolytically
IPC: C23G1/28
Filed: 1962-08-30
Abstract: <PICT:0995263/C6-C7/1> Metal surfaces, especially nickel-iron alloys and stainless steel, are freed from scale by treating in an electrolytic bath consisting of a fused mixture at 600-1000  DEG F. of sodium sulphate and sodium hydroxide, preferably containing 6-18% Na2SO4.  Voltage applied is 1-7.5 V., at a C.D. of -5 to 3 A.S.Z. The electrolysis effects reduction of sodium sulphate to sulphite, pyrosulphite, dithionate, thiosulphate, sulphide and like compounds which are effective in removing the oxide scale.  These compounds may be used to replace part of the Na2SO4 in the initial bath mixture.  A protective layer of carbon may be floated on the surface of the bath. The metal to be treated is immersed in the catholyte which is of larger volume than the anode space, the latter preferably being in the form of a separate insertable unit.  For example a tank 9 containing the fused electrolyte 15, is provided with a steel housing 10 with an anode 12 having an ion permeable diaphragm 11 in the wall facing the cathode 13.  A number of such anode units (called "cyclotrons") may be used.  Preferably the frame and diaphragm are connected to a low potential positive terminal to passivate these metal structures in the electrolyte.  The main power is 4 volts at 40 amps, and the passivating source is less, e.g. 2 volts at 2 amps. The submerged cathode lead is protected by a zirconium metal sheath.  The cathode may be of Cu, Ni, Ag, Zr, or Mo, and the anode of Fe, Ni, or Co, the diaphragm is a perforated sheet of Fe, Ni or Zr.  In examples corroded sheets of stainless steel, titanium, copper or silicon steels, are treated and then washed, first in water then in acid, e.g. H2SO4 or HNO3 and HF, and finally washed with water.

Title: Improvements in apparatus for wrapping articles
IPC: B65B59/00
Filed: 1948-12-30
Abstract: 674,942. Endless conveyers. BRECKNELL, MUNRO & ROGERS. Ltd., and DOLMAN. H. J. March 28, 1950. [Dec. 30, 1948] No. 33464/48. Class 78 (i). [Also in Group XVII] Articles 92 are pushed along the bed 2. 3 of a wrapping machine (see Group XVII) by pushers 12 carried on rods 10, 11 between endless conveyer chains 8, 9. Members 76 pivoted on the rods 10 are adapted to hold the wrapper on the article when rear extensions of the members engage stationary cams 78. The conveyer is given a forward movement, stopped, then moved back, a distance less than the forward movement, so that the pushers 12 disengage the articles, and then moved forward again by ratchet and double pawl mechanism. This mechanism comprises an arm 13 pivoted about an axis 14 and oscillated through a linkage 28 by a cam 24 on a motor shaft 23. The arm carries two independent pawls 15, 16 which cooperate with indents 17, 18 in a wheel 19 to oscillate the wheel and thus drive the conveyer, through a chain 20, forwards and backwards respectively. For the first part of the rearward movement of the arm 13 the pawl 15 is held out of engagement with the wheel 19 by a pin 96 on the pawl riding on a fixed ramp 97 so that, for this first part of the rearward oscillation of the arm, the wheel 19 and thus the conveyer is stationary, the wheel 19 being driven backwards for the remainder of the rearward movement of the arm. A non-return pawl 98 may be provided. An alternative form of conveyer drive, according to the provisional Specification may comprise two Geneva motions working in opposite directions.
Patent GB-334727-A (GB)
Abstract: 334,727. Krupp Akt.-Ges., F. Oct. 8, 1928, [Convention date]. Keyboard interlocks.-The hammer of a cash register or like machine is provided, in addition to the normal actuating-means, with manual actuating-means for use in repeat printing. The manual means may be adapted to be operated one or more times, or may be prevented by an interlock from being operated more than once after each normal operation; further, an inter-' lock may be provided to compel operation of the manual means after each normal operation. In the mechanism shown in Figs. 1 and 2, the hammer 1 has pins 2 engaging guide-slots 3 and is connected to a rocking frame 5 having an arm 10 abutting on a member 8 attached to a rocking arm 8<1> which co-operates with a cam 13, a spring 14 being arranged between the arm 8<1> and a seat 30 on the frame 5. A pivoted latch 18 engaging the frame 5 is connected to a rod 25 having a slot 22 engaging a pin 23 on the arm 8<1>. The cam-shaft 31 is geared to a driving-shaft 63 having a locking-arm 62 normally engaging an arm 61 connected to a movable segment 67, release of the driving-shaft being effected by depressing one of a number of release, keys 56 co-operating with the segment. The release keys 56 displace a segment 65 carrying bell-cranks 79 which co-operate with pins 66 on the release keys to prevent a second operation thereof. On operation of the driving-shaft, the cam-shaft makes one revolution and the arm 8' is rocked three times by the cam and a returning-spring 11, the spring 14 being compressed to operate the hammer on release of the latch each time the arm is raised. After the above-described operation of the hammer, it can be operated one or more times by moving forwards a hand-lever 33, the arm 8<1> having a part 37 in the path of an arm 36 connected to the hand-lever. A full-stroke pawl 42 co-operates with teeth 39 on the hand-lever. To lock the hand-lever during normal operation of the machine, and to prevent the hand-lever from being operated more than once after each normal operation, the hand-lever may be normally locked by a slide 47 having a hook 44 co-operating with a pin 43 on the hand-lever. When the cam-shaft has almost completed a revolution, a cam 48 moves the slide rearwards to release the handlever and a catch 52 drops in front of a projector 54 to retain the slide. On moving forwards the hand-lever, the hammer is operated and a pin 55 on the hand-lever releases the catch, thereby permitting a spring to return the slide. To compel operation of the hand-lever after each normal operation of the machine, the segment 65 may be connected by linkage 69 to a forked arm 72 adapted to raise a rocking arm 74, a rocking catch 70 retaining the arm in raised position and thereby preventing return of the segment. On operation of the hand-lever 33, a cam 85 thereon rocks the catch, and the segment returns to normal position to permit operation of the release keys.

Abstract: 1,211,820. Injection moulding sun visors; seaming non - metallic sheet material. GENERAL MOTORS CORP. 3 July, 1969 [8 July, 1968], No. 33631/69. Headings B5A and B5K. [Also in Division B7] A stun visor for a motor vehicle is made by injecting a fluent foamable material such as liquid polyurethane from an injector device 58 through a cylindrical end passage (38) in the visor support member 30 into a plastics cover held between die members 54, 56. The air is vented through a passage 42 in the end 32 of the member 30, this passage being sufficiently narrow to prevent escape of the polyurethane foam, which sets to a semi-rigid plastics foam material. The plastics cover is made by superimposing two sheets of polyvinyl chloride, for example, one above the other and placing them between upper and lower electrodes of a dielectric embossing press (Fig. 5, not shown) having a high frequency alternating current generator operating at a frequency of 1-100 mHz. The upper electrode is formed with a blade of the required shape for the sun visor body 16. On closure of the press, seams 22, 26 and 28 are formed, leaving two gaps 52 for the support member and also leaving the longitudinal edge adjacent this member unsealed. The support member is then positioned and the unsealed longitudinal edges are sealed using a dielectric  embossing press.

Title: Manufacture of Laminated Articles
Inventor: GILBERT DAVID STONE
IPC: B29C44/30
Filed: 1967-07-21
Abstract: 1,190,103. Laminating. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 July, 1968 [21 July, 1967], No. 33702/67. Heading B5N. In a method of making a laminate comprising a layer of foamed plastics, which is foamed between upper and lower facing sheets, e.g. of paper, plastics material, metal, rubber or paperboard, the upper facing sheet is urged downwardly into contact with the foam layer, before the rise of the foam-forming ingredients is complete, by resilient means, the latter acting across the full width of the upper facing sheet as the assembly of layers is conveyed beneath the means. The means may comprise a roller covered with resilient material, e.g. plastics foam, or a brush urged downwardly by a spring, or a strip of resilient metal, which may be of steel and may be of curved section, so that its lower part makes tangential contact with the upper facing sheet. Preferably, the operative part of the means, i.e. that part which presses on the upper facing sheet, has an appreciable extent in the direction of motion of the layers; if a spring-loaded brush is used, the dimension of the brush in this direction is selected accordingly; if a curved resilient strip is used, either its terminal portion is arranged to make contact with an appreciable area of the upper facing sheet, or two adjacent strips are provided. Before the upper sheet passes beneath the resilient means, this sheet may pass beneath a roller (13), Figs. 2 and 3 (not shown), the position of the roller being such that the upper facing sheet is slightly spaced from the layer of foam-forming constituents at this point. Both the roller and the resilient means may be mounted for adjustment of their vertical position. For assisting foam-formation, heaters, e.g. infra-red heating elements or a microwave tunnel heater, may be provided. The edges of the lower facing sheet may be folded up to form a tray for the foam layer. The foam layer may be of polyurethane.

Title: An improved process for the destructive hydrogenation of solid carbonaceous materials
IPC: C10G1/00
Filed: 1930-11-10
Abstract: Carbonaceous materials such as coal and lignite are subjected, prior to destructive hydrogenation, to a mild oxidation to reduce their caking properties.  The material is ground finely and treated with hot air or other oxygen-containing gas at 250-650 DEG  F. for several hours.  Higher temperatures and finer grinding shorten the period necessary.  The treated material may be mixed with water and heavy oil, so that the mineral matter separates out, while a paste of oil and coal or lignite remains, which may be destructively hydrogenated in known manner.

Abstract: 838,352. Sensing record cards; automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 22, 1958 [Oct. 24, 1957], No. 33774/58. Class 106 (1). [Also in Groups XXXVI and XL (b)] Magnetic marks on a statistical record are sensed by a member composed of a semiconductor material which is irradiated by a source of light, current conductors being attached to the semi-conductor and a potential appears between them whenever the semiconductor is subject to a magnetic field due to a marking on the record. In the form of Fig. 1 the semi-conductor 11 is carried on a support 10 at right-angles to the record 12. Conductors 14 are fixed on either side of the layer 11 and the line between them is illuminated by a slit of light from a lamp 15. When a semi-conductor is subjected to a magnetic field and to illumination in directions at right-angles a voltage appears in a third direction at right-angles to the other two. The presence of a mark on record 12 is indicated by a voltage between the conductors 14. The semi-conductor 11 and its support 10 may lie flat on the record being illuminated from above. In this case the horizontal component of the magnetic field associated with a mark is sensed. In the form of Figs. 3 and 4 a transparent support 23 carries spaced paralleled semi-conductor layers 25-30 separated by conductors, 31-35. Further conductors 36, 37 are disposed along the outside edges. Lamp 38 throws a slit of light across the layers and magnetized characters 39 are passed under the slit so that voltages are developed across layers 25-30 according to the portions of the character disposed beneath them. The outputs from conductors 31-37 are passed via wires 40-46 to decoding circuitry (not described).

Abstract: 1514506 Making light-sensitive printing plates HOECHST AG 15 Aug 1975 [19 Aug 1974] 34041/75 Heading G2X A process for producing a ligh-sensitive printing plate comprises forming an impression with a finemeshed screen on a coating of ligh-sensitive material on an opaque carrier, the coating being wet with a liquid in which the light-sensitive material is soluble. As shown, the carrier 2 passes over a rotating drum 1, and a coating 6 of the lightsensitive material is applied to it from a dispenser 3. A fine-meshed net 7 is formed as an endless web passing round rollers 4, and this is brought into contact with the coating 6 so that the mesh pattern is impressed thereon. The mesh may be made of fine metal wires or plastic fibres, and preferably has a mesh density of from 20-200 meshes per cm. The structural coating 6' then passes to a drying chamber 10, while the mesh is passed through a cleaning bath 5. In an alternative arrangement, Fig. 1a (not shown) the coating is applied to the carrier through the mesh. In a further alternative arrangement, Fig. 2 (not shown) the coating is already dry before coming into contact with the mesh, which is then wetted with a solution in which the coating is soluble. The printing plate so produced is suitable for the reproduction of continuous tones without necessitating the use of a half-tone screen.
